Well, since I am looking for information that is likely several years old. As-is, I find I am not having much luck. Anyone know if it is possible to get Earthbound decently playable on either SNESAdvance, or Snezziboy? I haven't had any luck personally with SNESAdvance, and Snezzi doesn't seem to like my 64 bit OS. So, shot in the dark, but anyone here know?

I believe the trick to earthbound was to create a new game then save on a PC emulator then transfer the save over to SNESadvance as the opening was completely impassible... may have to transfer the save back and forth on a few other occasions too...

Honestly I can hardly remember... It's been many years, at the time I was fairly involved in the scene (coded many of the speed hacks SNESadvance used to by-pass wait cycles or by-pass SPU700 checks)
